BED-SPRING comm To all whomz'tmag concern: .K

Be it vknown that I, FRAN;K Kusrnnnn, ;a citizen of "theU-nited States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, Ehave '-invented==:certain new and useful. Improvements ain- Bed- Spring Corners; ofi which' the following :isa V specification- My invention relates "to improvementsiin b'edspring corners and is of particular service when used: in connection with lhed springs in" which the :bed bottom comprisesa wire mightotherwise goxto 'waste in case it were- 'The'iprincipalobjects of thei nvention are to provide a corner-connectionbetween the side" members "and the I cross members or end members of .thespring frame, t-he' arrangement being such that the resiliency-of the loed bottom fabric will serve tomaintain the various parts-in position; to provide a corner of theclassdescribedwh-ich maybe constructed ofqrelat ivelyicheap material which not so-utilized; toproyidea corner of the class described in which the corners-may be'made accurately to sizeand may beassemhled together rapidly I and efficiently ;ito Y. provide acorner of the class described which may be constructed of metal not lialoleto break when subjected to shocks or sudden stresses; to provide a-sc'orner of the class described which shallbe neat, simplexand practical in design and inexpensive to manufactime, and in general towprovide an improved corner .ofthe ch-aractenreferredto;

a In the drawings whichil-lustr'ate a spre ferred embodiment of myinvention, Figure 1 is -a side elevation of the corner as usedon a spring-- frame equipped with .a. wire :link' fabric, Fig. 2'is-r'a "section takenon the line 2-52 of Fig. 1.;

:11: connected to the frame by means of. hel1calsl2. The principalmembe'rs of the spring'frame are a pair ofside members the top fiangey'or leg, of the angle iron- '14;

whichxconstitutes one of the cross piecesor;

end-members of the spring frame; 15 designate's -.as a whole my improved corner, the function :of which is to connect together the cross piece 14 and-the side n emher 13,

while at the-same time'servi-ngas afbracket by which the spring frame is supported upon the side rail-10. 1 I 2 improved corner 15 is composed of two parts,-one of which is a length of angle iron :or otherflanged metal-foldedj-or bent to provide :a loop '16 in'which is located-the 7 end of-the side member -I-t will beobservedthat the sides 1:? and 18--of the corner are bent up parallel as shown, the flanges19 and 20substantially" abutting against each other asjshownat 21 and being cut-away at their lower ends'to'fitagainst the rounded :upper surface ofithe side tube-13. The cross plate 21'? is riveted as-indicatedatQQ to the abuttingnflanges 19 and 20 and thus maintains :the' parts 1 and18 of the corner in.

fixed and parallel relation; The-portionpf said cross plate below the 'rivets22'is' a1so out away-r01 conformed to fitthe upper: side of the-Ltuhe 13; while theouter' end of the said cross plate 19 ise'xtended a sufficient distance to overhang the side rail 10 of the ihedstea dr In 1orderto prevent; relative movement :of thespring f rame and the side rail 10, I preferto provide a small down ward projection 23011 the end of the-cross plate, thus preventing lateral movementce'f 'theicorner.

The angle ironcross piece-14 is secured-"to the-corner 15 by means ofxa pair of'spaced apart vertically extending slotsQ il-whichieceive a pair: of similarly spaced lugs 25 V on the upright parts li and l8 of 'the corner. It-will he observed that thetension o'f the spring-12 serves to maintain-the angle iron tion.

l t in engagement with the said lugs 25, while angular movement of the corner in a vertical and longitudinal plane is prevented by reason of the extreme end of the tube 13 engaging the interior of the loop 16, the upper surface of the tube 13 being engaged also by the cross plate 21 and the cut away lower ends of the flanges l9 and 20. V

Rotation of the corner upon and around the axis of the side tube 13, is prevented by means of a pin 26 riveted to the loop 16 as shown at 27, said pin 26 fitting within the open ended slot 28 cut into thevend of the cross tube 13. Said pin 26 also prevents the corner from sliding along the tube. The scope of the invention should be determined by reference 'to the appended claims, in view of the fact that the described details of mechanical construction may be modified to suit individual requirements without sacrificing the benefits of the inven- I claimcombination with a longitudinal side mem berof a riser mounted on th end thereof and comprising an angle iron, l. shaped in cross-section, and having an intermediate portion of one of the flanges cut away and the other flange bent intermediately around the under side of the longitudinal member and extending upwardly thereabove at each side thereof, so that the remaining portions of the first mentioned flange engage the top f the side member at a distance from the end of said side member, to cooperate with the bent portion of the other flange to clamp theend between.

2. In a structure of the class described, the combination with a longitudinal side member of a plate bent intermediate of its ends to afford a riser engaging under the v endof the longitudinal-member, and having spaced upright legs at each side thereof extending thereabove, and a transverse connector secured at theinner ends of the up-' right legs to hold said legs in separated relation and engaging over the longitudinal member at'a distance from'the end to clamp the end of the longitudinal member between the transverse connector and the looped portion of the plate underlying the end of the longitudinal member, said transverse connector being extended laterally to engage a support at the side of the longitudinal member.

3. In combination, a tubular side member, an angle iron cross piece and means connecting said parts comprising a length of strip metal folded to fit and include the end of said tubular side member, the said strip having its ends flanged, the flanges abutting against each other when the strip is folded, means preventing separation of the said of the longitudinal member therecentrally folded to include and fit the end of the said tube, its ends being upturned and substantially parallel and provided with opposed flanges and lying substantially in the same vertical plane, one of said ends having a lug entering the aperture in said angle iron for maintaining the latter in fixed relation, a bed fabric resiliently connected to the horizontal leg of said angle iron remote from said lug whereby the angle iron is maintained in engagement with said lug, anda cross .plate united to both of said flanges and having an outer extension rest ing upon the said rail.

5. In combination, a supporting rail, a tubular side frame member, an angle iron cross piece having a vertical leg provided with an aperture, a length of strip metal centrally folded to include and fit the end of the said tube, its endsbeing upturned and substantially parallel and provided with opposed flanges, against each other, a lug on one of said parallel ends entering the aperture in said angle iron for maintaining the latter in fixed relation, a'bed fabric resiliently connected to the horizontal leg of said angle iron re? "mote from said lug whereby the'angle iron is maintained in engagement with said lug, a cross plate united/to both of said flanges and having an outer extension resting upon the said rail and means for preventing movement of said strip on the end of said side member.

7. In a bed, the combination With'a side rail and a longitudinal bed bottom member, of a riser on the end of said member comprising an angle iron, L shaped in cross section, having one flange thereof cut away intermediate of the ends, and the other flange bent intermediately to embrace the underside of the longitudinal member, and having the remaining portions of the first mentioned flange extended over the longitudinal v member and a transverse member secured 10 to said'remaining flange portions at, laterally spaced points and projecting laterally from the riser over the rail so as to be supported by said rail.
